Here, we explore the potential link between nicotine and PPARbeta/delta and report that nicotine increases the expression of PPARbeta/delta protein; this effect was blocked by an alpha7 nAChR antagonist (alpha-bungarotoxin), by alpha7 nAChR short interfering RNA, and by inhibitors of phosphatidylinositol 3-kinase (PI3K; wortmannin and LY294002) and mammalian target of rapamycin (mTOR; rapamycin).

J Pharmacol Sci. 2010 Mar 19;112(3):265-72. Epub 2010 Feb 20.

Analyses with receptor antagonists and kinase inhibitors revealed that the effects of chronic nicotine treatment are mediated by nicotinic receptors and their downstream effectors including phosphatidylinositol 3-kinase.

Abeta peptides and nicotine differentially activate several intracellular signaling pathways, including the phosphatidylinositol 3-kinase/v-akt murine thymoma viral oncogene homolog pathway, the extracellular signal-regulated kinase/mitogen-activated protein kinase, and JAK-2/STAT-3 pathways.

Nicotine-induced protection was blocked by an alpha7 nAChR antagonist, a phosphatidylinositol 3-kinase (PI3K) inhibitor, and an Src inhibitor.

Furthermore, nicotine induced activation of AKT and MAPK pathways, while inhibition of MAPK using U0126 and AKT by phosphatidylinositol 3-kinase inhibitor, LY294002, in part, blocked the antiapoptotic effects of nicotine against cisplatin and etoposide-induced apoptosis in NC.

Furthermore, a phosphatidylinositol 3-kinase (PI3K) inhibitor also suppressed the neuroprotective effect of the AChE inhibitors.
